1. Combine the butter, sugars, and glucose in the bowl of a stand mixer fitted with the paddle attachment and cream together on medium-high for 2 to 3 minutes. scrape down the sides of the bowl, add the egg and vanilla, and beat for 7 to 8 minutes. (see page 27 for notes on this process.)

2. Reduce the speed to low and add the flour, baking powder, baking soda, and salt. mix just until the dough comes together, no longer than 1 minute. (do not walk away from the machine during this step, or you will risk over mixing the dough.) scrape down the sides of the bowl with a spatula.

3. Still on low speed, add the chocolate chips, butterscotch chips, graham crust, oats, and coffee and mix just until incorporated, about 30 seconds. add the potato chips and pretzels and paddle, still on low speed, until just incorporated. be careful not to over mix or break too many of the pretzels or potato chips. you deserve a pat on the back if one of your cookies bakes off with a whole pretzel standing up in the center.

4. Using a 2 3/4 oz ice cream scoop (or a 1/3 cup measure), portion out the dough onto a parchment-lined sheet pan. pat the tops of the cookie dough domes flat. wrap the sheet pan tightly in plastic wrap and refrigerate for at least 1 hour, or up to 1 week. do not bake your cookies from room temperature— they will not bake properly.

5. Heat the oven to 375°f.

6. Arrange the chilled dough a minimum of 4 inches apart on parchment- or silpat-lined sheet pans. bake for 18 minutes. the cookies will puff, crackle, and spread. after 18 minutes, they should be very faintly browned on the edges yet still bright yellow in the center. give them an extra minute or so if that’s not the case.

7. Cool the cookies completely on the sheet pans before transferring to a plate or an airtight container for storage. at room temp, cookies will keep fresh for 5 days; in the freezer, they will keep for 1 month.

* You can substitute 18 g (1 tablespoon) corn syrup for the glucose.

** For the “coffee grounds” in this cookie, it doesn’t make a difference what kind you use. Just make sure you don’t use instant coffee; it will dissolve in the baking process and ruin the cookies. Also, never use wet, sogalicious grounds that have already brewed a pot of coffee.

*** Milk Bar uses cape cod potato chips because they aren’t paper-thin, and so they do not break down too much in the mixing process.

2. Whisk the butter and heavy cream together. add to the dry ingredients and toss again to evenly distribute. the butter will act as glue, adhering to the dry ingredients and turning the mixture into a bunch of small clusters. the mixture should hold its shape if squeezed tightly in the palm of your hand. if it is not moist enough to do so, melt an additional 14 to 25 g (1 to 1½ table- spoons) butter and mix it in.

3. Deploy as directed in recipe. the crust is easiest to mold just after mixing. stored in an airtight container, graham crust will keep fresh for 1 week at room temperature or for 1 month in the fridge or freezer.
